She said: "The news is finally out about my new role. I am over the moon about this. I loved the first series with Lacey Turner in it, and can’t wait for my next big challenge and where it will take me.

"I can’t really tell you much about the character I am playing, as its all still pretty hush hush, but when I can I will let you know."

Filming on the second series of Our Girl starts in January, and it will be screened in late 2016.

The first series, which attracted 6.3 ­million viewers, followed a different medic – Molly Dawes in Afghanistan – played by Lacey Turner , who has since returned to EastEnders.
